http://pear.php.net is now using jQuery for some sections of the administration area in order to view user notes/comments and that I will be starting implementing more sections over the site within the next few weeks (Of course this will all be done once we have split the code completely into templates, views, controllers, MDB2 move, etc)

He also makes some comments about the number of Javascript frameworks out there and a mention of the roadmap for the rest of the features they plan to add to the PEAR site.
